Heading Elements
These HTML elements set headings in a document. The h1 element is the HTML tag for largest heading. You can use h1 for the main titles, h2 element for section titles, and h3 for smaller sub-sections. 
Tip: the use of headings is highly recommended since search engines use them to index websites.
 Example    
<h1>Heading text - Level 1. Most Important Heading</h1>
<h2>Heading text - Level 2</h2>
<h3>Heading text - Level 3</h3>
<h4>Heading text - Level 4</h4>
<h5>Heading text - Level 5</h5>
<h6>Heading text - Level 6. Least Important Heading</h6>Note: web browsers normally add top and bottom margins to the content for every heading tag in HTML. Also, they set their text content to a bolder font.
align
It sets the horizontal alignment of the heading elements.
Tip: HTML5 does not support align. You should use CSS text-align property instead.
 Example    
<h1 align="center">Random text - Level 1</h1>
<h2 align="right">Random text - Level 2</h2>
<h3 align="right">Random text - Level 3</h3>
<h4 align="justify">Random text - Level 4</h4>
<h5 align="left">Random text - Level 5</h5>
<h6 align="center">Random text - Level 6</h6>Browser support
